Todllwhom-Zt may concern:

Be it known that FRAXLIR Lwsnrn, deceased, a citizen of the United States, and late of the city of Utiea, county of Oneida, State of New York, has invented new and useful Improvements in Knitting-ltlachineg 'of which. the following is n specification.

The invention relates to. circular rib knitting machines particularly adapted for spring needles and consists in means for supportin adjusting and operating the cylinders, particularly in means for separating the "cylinders more conveniently to put on the cloth at'the. beginning of opera tions and means for throwing certain parts out otoperation while the cloth is being put on and the machine started.

The ii'nportant features of the invention are a'single central standard carrying a solid, main table on whicl rnre supporteilthe cylinders, the driringnienns and rill pu whereby the usual operation of the n'nichine is elfected. All 'snidjipzirts illO arranged above this-table except the main drive-shaft, the bracket therefor zindsthe iul ncent parts. From this table rise two-posts, one having lateral extensions at its upper end, uftording a. firm threepoint support for the upper table which curries the upper cylinder, its

gear, needle cams, etc;

The lower or main table 18 provided with .21 conipzu'nlii'ely sniall oen l'itl bearing for the hub of the lower cylinder gear. so that the. supporting standard and lower table may he it-signed and made of stni'idnrd size for l'lltl lllliQS lini ing (lill'ere'nt size cylinders.

As a new feature; means are provided for separating the ovlinders 2i substantial space for convenience in initially starting the o'pcrntion of knitting' the tube of fabric, which consists in applying :1 piece of old fabric to one set of needles. threzuling up the various pa rts. commencing operations and arranging the various parts that they will cooper ate- :ind continue knitting w en the power is applied, commonly called"putting on the cloth. This separation of the cylinder edges a substantial space, in which the workman can conveniently operate, is preferably ell'ccted by raising the upper table and this Specification of Letters Patent.

F ram and supporting parts for UN} tables,

(Figs. 1, 2, 3.)1 indic ates the single-central'standard having the enlar ed 5 to stand securely on the floor of, t e mill and 2 screws 3. The standard-top is en above firmly to car .the lower-"table Agthue supportmg.- ;frame for g ls and fitted around the cam sleeve D; 0 this 30 lower gear is secured by cap-screws 9 the lower cylinder casting E on which is shrunk the lower cylinder F, slotted for the lower needles 11 and jacks 12, held in position by elastic encircling bands 13. H is the matrix .35 ring shrunk on to the lower cylinder and having its uppcredge notched at 15 (Fig. 4

to receive the rimar needles while the yarn isbein fe into t em by the sinkers 16 carried by t e sinker-bed J which is con- 0 solidated with the lower cylinder and matrix rin so as to revolve therewith. I These sin ers are actuated by the slur-cock 18 carried inthe sinker-bed cap 19 rigidly supported on posts L and K. Said post L and 5. the extens ons K of post K afford a firm,

three-point support for the upper table B formed with the bearing 20 to which is fitted the upper cylinder ear M. To this is secured by screws "21 t e upper cylinder cast:

50. ing N on which is shrunk the u per cylinder G provided with needles 22 acks 23 and circular bands 13 corresponding to similar parts fitted to thelower cylindey. He has omitted on the right but shown 'on the left the cam brackets and cams for operating the needles. 25 is the. lower cam and 26 the lower cam bracket supported on table A {27 are the upper cams and 28 the upper cam brackets bolted to the under surface of upper 0 table B.

Means for adjusting the up er cylinder, ,(Figs. 2, 3, 10, 11.) -Where a ifi'erent yarn is to be used ora slight chan e made in the stitch, it is necessary sligh reference to parts, all of which are-arranged in'g the post-cap, to raise or the lower. Heretofore means have been gested for adjusting the upper cylinder sea as slotted supports and adjusting screwsengagin with parts connected to the upper cylin er, but such means re uired an experienced mechanic and care ul manipulation, aided by a gage at'each change in ad I justment, and there was always danger of getting the parts slightly out of level and out of concentriclty.

He has devised means by which the upper table carrying the upper cylinder is adjusted initially with a solute accuracy with reference to the lower and thereafter changes in adjustment may easily be made by the ordinary operator without any. danger of getting the arts out of true.

- "The weig t of the upper table is sup *ported on the hollow posts K and L but is f raised to separate the upper cylinder from thelower initially 'in putting on the cloth by means ofthe raising rods 2: 2: extending from the raising member upwardly t3 the upper table. The front rod a: extends through post L, the two rear rods to extend on each side of the rear post K throu h the extensions K. To the upper end o each of said rods is fitted the guiding stud 29 having the thread30 forthe graduated fpost cap 32 which rests on the u per end 0 the post. The stud is provide with shoulder 34 on which rests the hollow washer 35. B

means of nut 36' and washer 38 the table is clamped securely on the hollow washer and thus to the stud. This is best shown in Fig.

) 10. Initially the tables and cylinders are adjusted with great care to be absolutely true, that is concentric and parallel, and 5 when this has beeir done the point 40 is marked on washer 35 to corres 0nd to the zero on cap 32, the cap being 0 amped fast by set-screw 41, having a soft leather plug 41 between the screw and the thread to protect thelatter. See Fig. 10.

When it is desired to raise the upper cylinder, thatis to readjust it with reference to the lower, it is only necessary to loosen the set-screws of the post-caps 32 and shift the latter each a certain number of scale spaces (marked on the post-caps) with reference to the point 40 on the washer 35. See Fig. 11. The post-ca post and tlierefore, when the former is turned, it is evident that it will raise the table and separate the cylinder edges; this is easily done by the workman of ordinary skill without possibility of-disturbing the parallelism or concentricity of the cylinders, for all that is necessary is to turn each postcap the same number of spaces of the scale, and the correctness of such adjustment is easily observed by the foreman. For rotattherein as shown in Fig. 11. The liftin rod rests on the upper end of the' wrench holes are provided.

' so that it may be slightly raised therefrom as the post-cap is turned. It will be understood that initially-the cylinders are adjusted with minimum space between them so that the-upper israised for separation, and may 'be lowered by turning the post-caps in the reverse direction to again bring the cylinders 'together. Aver-y delicate adjustment is possible, or instance-thefthread'30-may be made 10 510 to t" e'inch 'f-s'iiiile of 100 inscribed on the pofst-eep, which, permits an adjustment tothebn-thousandth of an inch. i

'. :He has shownin' Fig. a. desirable means lower- 'iend' 'of the stud correspondingly for fitting the studs to the rod. The upper end of the rod; :2; is fornied'with a beveled shoulder 45] and a threaded" tip 46 and the formedwith abevel and a threaded'sock'et,

-' so -that, when' screwed together, correct,

alinemnt is insured. It would-be simpler to form the stud and the lifting rod in one piece, that is' continuous, but then it would e. very inconvenient to take. the machine sapart', -so a connection is formed between them by means of the thread 46, to permit the rod-t0 be backed oil from the stud by't e wrench from below. .When'youtighten this-connection the bevel-insures accurate centerin "Thea ove described" construction of ad justing parts is preferably to the slight modificatoii thereof shown at the upper left handz corner of Fig. 3, where thestud and the lifting have a. butt-end-joint at c .witha tipxon one part fitting a socket on the other; If the parts are/not" absolutely true all, times secured' against lateral Idispla ce r, Means for raising the amber table .when

the cloth'jis being put on, (Figs; 1,: 2, 3.)'

On thesid'e of the standard-top" 2 there is provided a horizontal bearing' iS for crankshaft 51 9 having angular shank 5O on outer end for the crank and-a miter gear 52 on its inner end meshing .with interiorly threaded miter gear 53, which rests on the tubular portion,55 in the interior of standard 2 provided,to receive the threaded lifting rod 56,

gear 53 being internally threaded to mesh -w ithth e-thread on red This lifting rod extends downwardlyzin said tubular portion and carries rigidly fixed to its upper end the yoke 1 At its front end this yoke carries one of the three raising rods .7: and on the crossaim 58 at its rear end the other two rods :0, which'rods are fitted at their upper ends to the studs 29, whereby-the upper table may be easilyraised "into. the position shown in Fig. 1 to afford a manipulating space between the c linder edges. A space of two to three inc es or more is afi'orded" between the cylinders making it more convenient, particularlv for the ordinary operator to put on the cloth, so that much time is I saved. Butto do this successfully, it is betterto throw the lower needles out, of operation until the old cloth has-been run oil the up1')er.-needles, thus avoiding the crowd .ing of .the cloth on the two-sets of needles vith danger of bending and breaking them.

The upper end of )ost L, also the bearing aredesirably split as hest shown in Figs. 1 andlO and provided i with ears 5}) for the clamping bolts $0 whereby the 'upper table is clamped down rigidly in operative position; 'lh e adjusting and supporting parts are adapted to permit of the cylinders being separated for putting on the cloth without in the least disturbing the adjustinent'of the cy'linders whentheyare-returned to operating position.

Means for shifting parts out of operative position while Imttin on the el0th, (l igs, 4:

lo 9.)]During the above described separation of the cylinders andwhile starting the out of operative position certain parts such 7 as the pressers, sink'ers, thread-guides and lower -needles,.and has devised, means for conveniently so shifting suchparts andthen returning them to ope'rative'p'o sitiomf The parts and the means for shifting -are as follows: 26 is the low'ercam bracket 5e cured by-its base on the lower table A and carrying the lower cam 25' hinged'orpi\'0t'-.

ally connected to the-bracket (31.; The upwardly extending arnrofbracket is provided withan opening to receive the sleeve 62 carrying'tliefplungelf;6&1having the handle 65 on itsfimter' end and forced in \v'ardly by the spring GG to -engage with a not-ch or hole 68 in the cam, holding the'latf ter up into operative:position; (Figs. 8 and '9). When the plunger is pulledout-against.

the foree of the spring the cam falls (as shown in dotted'lincs in Fig. that the needles as they reach this point are-not raised but remainout of action and away from the work. To restore the cam to operative position it is merely necessaryto'raise it by hand until the plunger engages with hole (38.

The upper cam brai'zli'ets carrying the upper cams 27 for the upper needles, are

bolted to the under surfaceof the uppelf table B. OIL-these brackets are secured the upper and lower presser brackets 7Q and-70' provided with horizontally extending bearing studs 72 to which are fitted sleeves 73 carrying the presser shanks 74 and the pros. scrs l" I". In the, end of each bracket s ar ranged a small plunger 76 adapted to engage with a hole 78 in the sleeve'to maintain the presser out of operative position when the cloth is being put on the machine and i I I machine, he has found it convenient to shift guides, permitting the latter also Y swung out of position during the said opera/= started. See Figs. 4 and 6. The non-operative osition is shown in dotted lines in Fig. 4. Evidently the plunger could be arranged in the sleeve and the holes made in the studs. In Figs. 4, 5 and-7 are also shown the matrix sinker supportingfand operatin' mechanism and the arrangement-o threa .tobe

tion of starting the A; As aforesaid H is the ring, 16 are the sinkers carried in thesin'ker bed J, and

19 is the sinker-bed cap, 18= and 18 are the slur-cock cams, 80 is astud clamped to cam 18. by nut 81, and 83' is a set=screw in said stud engaging with clip 84 on sinker-bed cap 19, whereby the position of the cam may be adjusted and the length-of the stitch be varied. 86 is an eccentric lever journaled on said stud whereby the slur-cook may bev withdrawn from working position carrying plunger, 91, helddown'inposition by spring '92 .in's'ocket'90, ha ving arm 1' whereby it is sinker-bed cap. thread guide out of operative position shown in Figs. 4 and 5, pull up the arm against the force of the spring to release from notch 94, or other locking means, said notch 94 being formed in the socket 90, and

the plunger 91 being provided with a pin or projection to engage with said notch and lock the guide in position, and give the guide a'quarterturnto swing it away from the needles, 'in which position the threadguide will rest on the cap, and be in a convenient position for threading. When in working position, it is difficult to thread the tube 88.

By considering the operation of putting on the cloth, the convenience of the above described means will be; evident. The steps of that operation are as follows: First, turn up all the pressers to be maintained by their locking plungers 76 away from the needles. Lift the thread guide by its sleeve and swing it around out of operative position. VVithdraw the slur-cock by the lever 86. Pull out the plunger 64 to drop the lower cam. Raise the upper table by means of the crank and lifting mechanism to carry the upper cylinder away from the lower. Hold the edge of the cloth up against the upper needles and turn, the cylinder till they all hook through the cloth. Then lower the upper cylinder, turn the thread guide into operative position, throw in the slur-cock, and

suitable clutch mechanlsxp pulley, and lock the. latter to the ring,

.of any .for starting To shift the then lower the pressers of the upper set. Then start the machine and run it till the 01d cloth is run off and the upper needles are knitting the new thread, then drop the pressers of the lower set and raise the lower cam into operative position, andcontinue knitting.

tribute to the production ofpracticall .perfect'wvork- Convenientaccess,toall arts is permitted by the simple central standard, without projections, whichis simple and economical to constructand'to install. This standardand the lowertable, carrying the front and rear posts form's strong, solid, compact, frame to carry the operating parts;

and said parts are thus carried on a three-- point support, which isthe lis't possible, for this gives" afirm support without'danger of springing as with a two point support, and

without danger ofwvarpingas may occur with a four point support where one point'is lower than the others. This supporting frame is also compact and permits easy ac? cess to all the operative parts for the rear post and its extensions are little wider than the spur-gear and hotlithe front and rear posts are arranged at a suilicient distance from the cylinders to afford space for the canrbrackets, sinker bed, sinker lied cup,
